They're yet to race side-by-side but Daniel Ricciardo is well aware there are plenty of Formula One fans counting down the days until he and teammate Sebastian Vettel fall out.
But while the Australian is promising to put up a fight, he says it'll all stay professional.
Sunday's Australian Grand Prix will be Ricciardo's first alongside four-time world champion Vettel in the Red Bull team after replacing compatriot Mark Webber.
Vettel and Webber shared a fierce rivalry in their five seasons together, but things soured in 2010 when the pair clashed - on and off the track - over an incident during the Turkish Grand Prix.
Relations reached an all-time low in Malaysia last year when Vettel ignored team orders not to overtake Webber, who was coasting to victory at the Sepang circuit.
